Mixed-Pattern Ameloblastoma of the Anterior Mandible: A Rare Histopathological Presentation at an Infrequent Location.

Ameloblastoma is a benign odontogenic tumor of epithelial origin that exhibits a locally aggressive behavior with a high level of recurrence and multiple factors involved in its molecular pathogenesis. This article is a case report of a 46-year-old male patient suffering from a progressively enlarging tumor of the anterior mandible that caused gradual expansion of the lingual cortical plate and root displacement without resorption of the involved teeth. Incisional biopsy was consistent with "conventional" ameloblastoma, showing a mixed pattern of both the follicular and acanthomatous subtypes.

Carcinoma Cuniculatum of the Maxilla Mimicking Nonhealing Extraction Sockets at the Right Molar Region - An Interesting Case.

Background: Carcinoma cuniculatum is a rare variant of squamous cell carcinoma, mostly affecting the skin but also sparsely reported to occur in the oral cavity. Oral carcinoma cuniculatum (OCC) tends to be misdiagnosed as verrucous carcinoma; this may lead to inadequate treatment and recurrence due to the locally aggressive nature of the tumor. This report presents the case of a 56-year-old man with a progressively enlarging painful OCC at the maxillary right molar region, exhibiting both exophytic (red, soft, nodular mass) and endophytic (superficial ulceration and bone exposure, mimicking nonhealing extraction sockets) growth patterns.

Acute Encephalitic Syndrome Induced by Scleromyxedema.

Dermato-neuro syndrome is a potentially fatal neurological complication of scleromyxedema consisting of fever, seizures, and coma. This is an overlooked scleromyxedema case of a 62-year-old female patient from 2-years ago. She was admitted to our ICU because of high fever, colloid speech, muscle ache, and nausea.

Fabrication of a 3D Printing Definitive Obturator Prosthesis: a Clinical Report.

Introduction: Digital technologies related to imaging and manufacturing provide the clinician with a wide variety of treatment options. Stereolithography (SLA) offers a simple and predictable way for an accurate reconstruction of congenital or acquired defects.

Clinical Case: A 65-years old cancer patient with non- keratinized squamous cell carcinoma of left maxillary sinus came for a prosthetic clinical evaluation.

TGF-β1, Smad-2/-3, Smad-1/-5/-8, and Smad-4 signaling factors are expressed in ameloblastomas, adenomatoid odontogenic tumors, and calcifying cystic odontogenic tumors: an immunohistochemical study.

Objectives: The TGF-β/Smad signaling pathway regulates diverse cellular functions, including tooth development, and is involved in numerous pathological processes such as tumorigenesis. The aim of this study was to investigate the immunoexpression of the TGF-β/Smad signaling pathway members in ameloblastoma (AM), calcifying cystic odontogenic tumor (CCOT), and adenomatoid odontogenic tumor (AOT).

Materials And Methods: This retrospective cross-sectional study included 65 tissue specimens: 34 AMs, 13 CCOTs, and 18 AOTs.
